Basic Twitter Oauth2 steps

Oauth2 Twitter Docs

Following these steps got an Oauth2 access token

Hit this URL

• CLIENT_ID Example: M1M5R3BMVy13QmpScXkzTUt5OE46MTpjaQ

• REDIRECT_URI Example: https://2xdzlqwmizkelr7naddet3nqau0gpuzd.lambda-url.us-east-1.on.aws/

Get the code from the query string params

• Example: MHk2RzZVdTcyaEVwVFFuS1RRendfLXBGVl9OQUNGNlZPa0Iwa1BWeWFKSEliOjE2NjA4Njg5NjI4NDg6MToxOmFjOjF

Next send a request like so

curl --location --request POST 'https://api.twitter.com/2/oauth2/token' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--header 'Authorization: Basic BASE64ENCODED'\
--data-urlencode 'code=CODE' \
--data-urlencode 'grant_type=authorization_code' \
--data-urlencode 'redirect_uri=REDIRECT_URI' \
--data-urlencode 'code_verifier=challenge'

• In the auth header goes a base64 encoded CLIENT_ID:CLIENT_SECRET

From that response you should get this

{
    "token_type": "bearer",
    "expires_in": 7200,
    "access_token": "ACCESS_TOKEN",
    "scope": "follows.read offline.access tweet.write users.read tweet.read",
    "refresh_token": "REFRESH_TOKEN"
}

Using the refresh token we can make a request like this to get another set of tokens

curl --location --request POST 'https://api.twitter.com/2/oauth2/token' \
--header 'Content-Type: application/x-www-form-urlencoded' \
--header 'Authorization: Basic BASE64ENCODED'\
--data-urlencode 'refresh_token=REFRESH_TOKEN'\
--data-urlencode 'grant_type=refresh_token'
